The Essential Guide to Project Management

Principais ideias

• Every project rests on six linked ideas, outcome, trade-offs, time, uncertainty, people and method, and a weakness in one shows up in the others.
• Agree with the sponsor which constraint is fixed and which will flex, because quietly cutting quality to hold a date usually returns as rework.
• Protect the finish date with a pooled buffer and extra care where paths merge, rather than padding every task and watching the padding vanish.
• Give estimates as ranges, keep a contingency for risks nobody has named yet, and expect the range to narrow as real work replaces guesses.
• Choose a plan-first or short-cycle approach by how stable the requirements are and how costly late change would be, not by fashion.

1. The map: six ideas and how they connect

   Most of project management can be organised under six ideas. Outcome is what the project must achieve and for whom.

2. Trade-offs: fix two, let one flex

   Time, cost and scope are linked: change one and at least one other moves. Quality sits in the middle, and it is the one most often cut in silence, because nobody sees the cut until later.

3. Time: dependencies, float and hidden slippage

   A schedule is a network of tasks linked by dependencies. The longest chain through it is the critical path, and any delay on that chain delays the finish.

4. Uncertainty: ranges, risks and the unknown

   A single-number estimate hides how much you do not know. A range tells the truth: six to ten weeks says more than eight weeks.

5. People: power, interest and the cost of talk

   Projects succeed or fail through people, and three ideas carry most of the weight. First, map stakeholders by power and interest.

6. Choosing a method, and what to ignore

   The sixth idea is method. A plan-first approach defines scope, schedule and budget up front and controls change carefully; it suits work where requirements are stable and late change is costly, such as construction or regulated submissions.
